The Open Source Development Labs has voiced cautious optimism that its latest initiative could finally herald a mass-market for Linux on the desktop. OSDL is pushing ahead with Project Portland, to develop a common set of core technical requirements for Linux and open source software on the desktop, following a meeting of 47 companies and organizations it hosted earlier this month. Portland has identified a core set of areas, spanning the interface, plug-and-play, drivers and the kernel, that OSDL members will flesh out.
